Section 7
Troubleshooting
If a fault should occur, first thoroughly study the symptom in order to be able to correctly judge the
reproducibility of a problem, and interaction with other associated equipment. Thus, find an appropriate
remedy.
7.1 IDRW head is directly connected to upstream
controller
7.1.1 No response (response not yet received), or, occurrence of ille-
gal characters
Check the following points.
Supply voltage (5 VDC
Cable connection (pin arrangement on the upstream controller side, wiring connection/disconnection of connection cable, etc.)
Communications protocol settings on upstream controller (Baud rate, data format)

7.1.2 Response is available (response code is other than "00")

According to the response code in response data, check the following points.
Error in communication with upstream controller side
Response code
"10"
"11"
"12"
